I loved the drama very much and the cast was really cool and lovely . The main couples had small misunderstandings very often but they didn't make their relation completely meaningless and the relation between each every character is very beautiful and the story pace is not too slow or too fast . aww xiao luo and princess relationship was the best in the whole drama and miss zhao was also very cool and strong woman . It's a must watch drama and about rewatch it's upto ourselves . it's about architecture in the ancient times with romance and it matched as the leads have same opinions even though male lead appear as cold but he is warm and really his laugh reminds of me of a baby .
